In end rail 12 is a junction passage 27 connecting the bores for manometer limbs 18a and 18?). For convenience in manufacture, the junction pas1 sage 27 is formed by drilling a hole through the rail 12 extending to bore 20 and sealing the outer end by a plug 28 Extending between and rotatably mounted in the end rails is a pair of rods 29a and 29b and having heads 30a and 30?) whereby they may be rotated. A similar pair of rods is provided on the other side of the tubes 18a and 18b. Mounted on brackets 31a and 31b is a scale 31 for taking readings of the actuated or indicating fluid in the manometer limbs. A like scale is similarly supported on the other pair of rods. These scales may be marked with characters arranged in any suitable manner. Bracket 31a is slidably mounted on the rods and bracket 31?) is threaded thereon. By turning the rods the scales may be raised or lowered to adjust their zero position. On the rods are pointers 32 encompassing the rods and slidably mounted thereon so that the pointers may be moved to any desired position and serving to conveniently mark any division on the scale. Two scales may be provided, one on each side for conveniencein taking the readings.

It will be noticed that, as shown in Fig. 1, plugs 33a and 33?) close the openings in end rail 12 corresponding to the openings in end rail 11 which are shown connected topipes 25a and 25b. The manometer bores in end rail 11 are closed by plugs 341a and 34b. The corresponding bores in end rail 12 are closed by plugs 85a and 356. It will also be noticed that the reduced portions of the manometer bores in end rail 12 are threaded as indicated by 36a and 36b.

The passages in the end rails are so arranged in Fig. 1, that pipe 25a may be con nected to one source of pressure to be measured and pipe 251) to the other. Indicating fluid is placed in manometer limbs 18a and 18b, and the glass limbs function in the usual manner of a manometer. If the indicating fluid is blown out of a manometer limb, it will encounter either a tie bolt 17a or 17?) which acts as a baflie, and will drop into the corresponding stile 10a or 10?), where it may be finally recovered by removing either plug 33a or 336. a

Referring to Fig. 6, the gauge is shown inverted and with passages in the end rails so arranged that there are two manometer gauges, each gauge employing one of the stiles as a limb. Plugs 35a and 35?) are removed from rail 12 and pipe nipples 37a and 37b substituted, the pipe nipples closing com munication of the manometer limb bores through junction passage 27 It will be noted that the pipe nipples are threaded into the tapped portions 360 and 36b of the bores,

and either pipe nipple would serve to close the junction passage. In end rail 11 plugs 38a and 88b replace pipe 25a and 25b. The plugs may merely be shifted. A different scale or set of scales indicated by 39 will be substituted, as the heights of the columns of indicating fluid in the manometer limbs 18a and 18?) are only visible. It will be noted that manometer tube 18a and stile 10a form limbs of one manometer to which connection is made to the sources of pressure to be measured by pipe 40a and nipple 3711. Similarly, the other manometer comprises limbs 10?) and 18b to which connection is made by pipe 40?) and nipple 371). Thus two manometers side by side are provided.

\Vhat I claim is 1. A gauge of the character described comprising a frame including side stiles formed of non-fragile material, end rails formed of non-fragile material, and a pair of manometer limbs disposed intermediate said stiles and extending between said rails: said stiles being tubular, said end rails being blocks and one having connection passages communicating with the manometer limbs and having outer ends adapted to be sealed or to be connected to a source of pressure to be measured, the other of said rails having a junction pas sage therein connecting the manometer limbs, and said other rail having bores communicating with said manometer limbs andadapted to be sealed or to be connected to a source of pressure to be measured.

2. A gauge of the character described comprising a frame including hollow side stiles adapted to formmanometer limbs, end rails, and a pair of manometer tubes forming manometer limbs disposed intermediate said stiles; said end rails being blocks and one having connection passages communicating with the manometer tubes and each connection passage having an outer end adapted to be sealed or to be connected to a. source of pressure to be measured, each of said pa-ssages crossing and communicating with the bore of stile; the other of said rails having a junction passage therein connecting the manometer tubes, and said other rail having bores communicating with said manometer limbs and adapted to be sealed or to be connected to a source of pressure to be measured.

3. A gauge of the character described comprising a frame including side stiles, end

rails, and a pair of manometer limbs disposed intermediate said stiles and extending between said rails: said stiles being tubular, said end rails being blocks and one having connection passages communicating with each manometer limb and each having an outer end adapted to be sealed or to be connected to a source of pressure to be measured, each of said passages crossing and communicating with the bore of a stile, the other of said rails having a'junction passage therein connectingthe manometer limbs, said other rail having bores Communicating with said manometer limbs and adapted tobe sealed 5 V or to be connected to a s'ource of pressure to be measured, thefirst mentioned rail having bores, one for each manometer limb communicating with a corresponding connection passage. 1 l V In Witness that I claim the foregoin If have hereunto subscribed'my name'this 2 th day of Ap'ri1,11929. v 1 MILTONTO, JENSEN. f
